Protecting Your Outboard Motor from Corrosion

If you are an experienced boater, you probably have experience with corrosion. This natural phenomenon can wreak havoc on almost every component of your boat. Because they are constantly exposed to the elements, outboard motors are especially vulnerable to corrosion. This guide from Riverview Sports & Marine explains how to prevent corrosion and extend the lifespan of your outboard motor.

What Are the Effects of Corrosion?

The most obvious sign of corrosion is visible rust on metal surfaces. You may also notice pitting, flaking, and discoloration in the metal, as well as leaking fluids. If your motor has experienced extensive corrosion, it will struggle to start and run properly.


The key is to catch corrosion early, before it causes irreversible damage. That's why it's important to take proactive steps to prevent corrosion.


What Is a Sacrificial Anode?

A sacrificial anode is a metal rod (usually made of zinc or aluminum) that is attached near the engine's exhaust port. As the sacrificial anode corrodes, it diverts corrosion away from other metal components on your boat.


All outboard motors come with sacrificial anodes. However, because they are designed to wear down over time, they will eventually need to be replaced. Make sure to check the condition of the anode on a regular basis, and replace it if needed.


Cleaning and Polishing Your Outboard Motor

Regularly cleaning and polishing your outboard motor is also necessary to prevent corrosion. Make sure to remove any dirt and algae deposits that may have developed on the metal surfaces, and smooth over any light scratches on the exterior. The user manual provided with your outboard motor will indicate which cleaning products to use.


What If My Outboard Motor is Already Corroded?

If any component of your outboard motor has succumbed to corrosion, it will need to be replaced. Visible signs of corrosion indicate that a part has been weakened, and may not be able to withstand further use.
